Description
In vmStructs.cpp MetablockTreeDictionary is defined twice. In vmStructs_cms.cpp AFLBinaryTreeDictionary is likewise defined twice. Looks like the code was introduced by 

7045397: NPG: Add freelists to class loader arenas.

This shows up when running jmap:

Attaching to process ID 25561, please wait...
Warning: the type "MetablockTreeDictionary" (declared in the remote VM in VMStructs::localHotSpotVMTypes) had its size declared as 32 twice. Continuing.

Server compiler detected.
JVM version is 25.0-b09

I think it still works, but it's not pretty.
